[0017] like Figure 1As shown in Figure 4, a hexagonal part positioning fixture device includes a body 1, a pad 2, a cylindrical pin 4, a double-ended stud 7, an adjustable support column 8, a movable pressure plate 9, and a shouldered hexagonal nut 10. A vertically oriented adjustable support column 8 is threaded to the middle position of each of the left and right sides of the top of the body 1. Between the two adjustable support columns 8, two vertically oriented and spaced-apart double-ended studs 7 are threaded to the top of the body 1. At the connection between the double-ended studs 7 and the body 1, a nut 6 is threaded onto each double-ended stud 7. The positions of the double-ended studs 7 and the adjustable support columns 8 on each side are adjacent, and the two double-ended studs 7 and the two adjustable support columns 8 are all on the same straight line. Between the two double-ended studs 7, the top of the body 1 is fixed by screws 3. There are two longitudinally arranged and spaced-apart pads 2; on the right side of the right pad 2, the top of the main body 1 is equipped with two vertically spaced cylindrical pins 4, and the right double-ended stud 7 is located in the middle position between the two cylindrical pins 4; on the rear side of the right pad 2, the top of the main body 1 is also equipped with a vertically spaced cylindrical pin 4; a movable pressure plate 9 is respectively installed on the upper end of the two double-ended studs 7, and the double-ended studs 7 are fitted through the waist-shaped holes on the movable pressure plates 9, and the ends of the two movable pressure plates 9 away from the pad 2 respectively fit and fasten to the top of the adjustable support column 8 on their respective sides; above the movable pressure plates 9, a shouldered hexagonal nut 10 is threadedly connected to each double-ended stud 7; two spaced-apart lifting bolts 5 are provided on both the front and rear sides of the main body 1.

[0018] During use, the main body 1, double-headed studs 7, adjustable support columns 8, and movable pressure plates 9 are all variable structures. The height of the main body 1, double-headed studs 7, adjustable support columns 8, and movable pressure plates 9 is determined according to the height of the part to be processed. During processing, the hexagonal part is placed on the two pads 2, and the two adjacent end faces of the hexagonal part are respectively pressed against the three positioning cylindrical pins 4. The movable pressure plate 9 is pressed against the upper surface of the hexagonal part. The adjustable support columns 8 are used to support and adjust the movable pressure plate 9.
